[Preparation for colonoscopy: a reliable and easily implemented regimen].

Three different colonoscopy preparation methods were tested in 150 out-patients who received colonoscopies, 50 in each group, a randomized prospective simple blind study. The original Golytely-recepture with three litres of liquid was tested against Clean Prep which has to be dissolved in four litres of liquid. Both receptures had the same isotonic salt solutions. The third group was a method with a laxans (X-Prep) including eating restriction lasting three days. The judgment criteria were the cleanliness of the bowel, the formation of foam and the subjective sensitivity of the patient during the preparation phase. The preparation with the three bags containing three litres of Golytely solution according to the original recepture proved to be the least troublesome for the patients and was the most efficient method when it came to cleanliness and the formation of foam. The costs of this preparation methods were lower than those of the other methods.
